Which ITSM process aims to minimize the negative impact of changes to the IT infrastructure?
- Asset Management
- Change Management
- Incident Management
- Problem Management
'Change Management' in ITSM focuses on controlling and managing changes to the IT infrastructure. It aims to minimize the negative impact of changes, ensuring that they are planned and implemented effectively.
In IT governance, the principle that ensures stakeholders' rights are protected and taken into consideration is called _______.
- Accountability
- Compliance
- Equity
- Transparency
In IT governance, the principle that ensures stakeholders' rights are protected and taken into consideration is 'equity.' This means that the interests and concerns of all stakeholders are fairly addressed, promoting fairness and inclusivity.
The process of gathering information about a target system to find vulnerabilities that can be exploited is called _______.
- Debugging
- Encryption
- Hacking
- Scanning
The process of gathering information about a target system to find vulnerabilities is known as 'Scanning.' It's a critical phase in penetration testing and security assessment.
In a O(nlog?n) sorting algorithm, the log?n typically indicates the use of a _______ process.
- Divide and Conquer
- Linear
- Parallel
- Recursive
In a sorting algorithm with a time complexity of O(nlog?n), the log?n typically indicates the use of a 'Divide and Conquer' process, where the problem is split into smaller subproblems and solved recursively.
An essential consideration for IoT security is ensuring the _______ of data as it is transferred from devices to servers.
- Availability
- Confidentiality
- Integrity
- Performance
IoT security requires data 'Integrity' to ensure that data remains unchanged during transmission from IoT devices to servers, preventing data tampering.
A project manager receives feedback from the quality team that certain features do not meet the quality standards. What should be the project manager's immediate step?
- Blame the quality team for the issues.
- Ignore the feedback and proceed with the project.
- Prioritize the project's schedule over quality.
- Review and address the quality issues.
When a project manager receives feedback from the quality team indicating quality issues, the immediate step should be to review and address these issues. Ignoring quality concerns can lead to project failure or costly rework later. It's crucial to ensure that the project meets the required quality standards to deliver a successful outcome.
Which ITSM framework is designed around five lifecycle stages: Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement?
- Agile
- DevOps
- ITIL
- Scrum
The ITSM framework that is structured around the five lifecycle stages mentioned is 'ITIL' (Information Technology Infrastructure Library). ITIL provides a comprehensive approach to IT service management.
The _______ is a protocol stack used in IoT to facilitate device-to-device, device-to-server, and server-to-server communication.
- HTML
- HTTP
- MQTT
- OSI Model
The 'MQTT (Message Queuing Telemetry Transport)' protocol stack is commonly used in IoT for facilitating communication between devices and servers. It's designed for efficient, lightweight messaging.
You are tasked with securely transmitting credit card data over the internet. Which cryptographic protocol would be most appropriate to ensure data integrity, confidentiality, and authentication?
- FTP
- MD5
- SHA-256
- SSL/TLS
The most appropriate cryptographic protocol for securely transmitting sensitive data like credit card information over the internet is 'SSL/TLS' (Secure Sockets Layer/Transport Layer Security). SSL/TLS provides data integrity, confidentiality, and authentication through encryption and certificates.
You are tasked with setting up a virtual environment where the virtual machines should have direct access to the physical hardware resources without much intervention from the host operating system. Which type of hypervisor would you opt for?
- Full Virtualization
- Paravirtualization
- Type 1 (Bare-Metal Hypervisor)
- Type 2 (Hosted Hypervisor)
In this scenario, a Type 1 hypervisor, also known as a bare-metal hypervisor, is the choice. It allows virtual machines to interact directly with physical hardware, making it a preferred choice for performance-critical environments.
